There is a free programming course here http://www.appinventor (The default color is white text on black but the color properties, as well as the text size, may be changed in the App Inventor Designer.) When this screen is displayed the user may touch an item in the list to select it. Use ListPicker whenever you have a set of items from which the user is expected to make a selection.

If so, it should be easy to meet your requirement, the problem is that you cannot multi-select from the ListPicker, you can only select one row at a time. However, if the total number of times you make a selection is always the same (in your example, three rows are selected) then you can display the ListPicker programmatically for the remaining two picks (via a Procedure, using call ListPicker Open)

In December, I was trying to get a listpicker to change lists and stay open. Eventually, I found out that couldn't happen and decided to switch between 2 listpickers, going back and forth as the lists change. I then ran into another problem, which was that the first listpicker was not switching lists, and it was only showing the preset list. I figured out that it was because of the set.listpicker block in the before picking event handler The ListPicker component shows the user some choices and lets her choose. It has an associated button. When the button is clicked, the chooser appears over the entire screen. The user chooses, and the UI reverts back to its previous state. The BeforePicking event is triggered when the user clicks the ListPicker's associated button. Generally you'll set the ListPicker's Elements property here. Elements is a list and its items are what appears in the chooser. In this sample, ListPicker.

Unfortunately, the Selection property of the ListPicker is the actual data (the note item), not the index, and the ListPicker component doesn't provide direct access to the index of the list (this will certainly be added in later versions of App Inventor). The workaround is to take advantage of another block in the list drawer, position in list. Given some text, this function will return the position of the first match to that text in a list. Usin
